Companion to Raft-Labs/raftkit-admin#3 — the OpenTelemetry receiver. Merge both; each is inert without the other.

Why

Telemetry only sees Claude Code. The hooks under raftkit-core/hooks/ build events and POST them to the admin API, but Cowork sessions have no hooks and no host filesystem — so PM and QA work, the whole reason raftkit-pm and raftkit-qa exist, is invisible.

Cowork has a first-party OpenTelemetry export instead, which an admin turns on once and which reports prompts, tool failures and errors with no help from any skill.

What it does not report is skills. Cowork emits no event when a skill runs — no tool result, no prompt, because a skill is expanded internally as a prompt (claude-code#41845, closed as not planned). The only trace a skill leaves is what it says.

The contract

Every pm and qa skill opens by naming itself:

Using raftkit-pm:brainstorm to turn this idea into a spec doc.

New raftkit-core/cowork-telemetry owns the shape, the disclosure and the boundaries. Each of the 13 skills carries a one-line bullet pointing at it — the same pattern the plain-language contract already uses.

The line earns its place regardless of measurement. Someone who asked a question and got a differently-shaped answer deserves to know which skill picked it up, and these skills change the shape of a reply a lot. That is also why it's plain text rather than a hidden marker: a tool that measures people shouldn't measure them invisibly.

This is not a write, and is not filed as one

The skill says a line in a conversation. It sends nothing — the admin-configured exporter is what leaves the machine. So nothing here goes near the draft → approve → push gate, and no entry is added to the automatic-write exception list; an entry there would license the next skill to POST somewhere. CW6 fails the build if one appears.

One line is the entire allowance. No skill calls an endpoint, spools a file, or reports anything itself, on any surface.

The opt-out needed correcting, not repeating

RAFTKIT_TELEMETRY=off sets an environment variable the hooks read, and there are no hooks in Cowork — so it does nothing there. house-rules, the README and the new skill now all say that plainly instead of implying an opt-out that silently fails. The real switch is the admin's OTLP endpoint; there is no per-session equivalent, and pretending otherwise would be worse than saying so.

Assistant responses are read for the announcement and for refusals, then dropped — never stored.

Verification

tests/cowork-telemetry.test.sh — CW1–CW10:

  • CW4 fails if any pm or qa skill lacks the contract
  • CW5 fails if a skill announces a name that isn't its own, which would file another skill's rows in the dashboard
  • CW6 fails if this ever gets written up as a write exception
  • CW8 fails if the opt-out is described as working in Cowork

Verified as a real gate: renaming one announcement fails CW5 by name. All 31 suites, validate.sh and check-plain-language.mjs green.

The behaviour itself — does the announcement actually survive into an assistant_response event — is only observable in a live Cowork session with the receiver deployed. That's the first thing to check after both merge.

…should say

## Why

Telemetry only sees Claude Code. The hooks under `raftkit-core/hooks/` build events and POST them to the admin API, but Cowork sessions have no hooks and no host filesystem — so PM and QA work, the whole reason raftkit-pm and raftkit-qa exist, is invisible.

Cowork has a first-party OpenTelemetry export instead, which an admin turns on once and which reports prompts, tool failures and errors with no help from any skill. The companion raftkit-admin PR receives it.

What that export does not report is skills. Cowork emits no event when a skill runs — no tool result, no prompt, because a skill is expanded internally as a prompt (anthropics/claude-code#41845, closed as not planned). The only trace a skill leaves is what it says.

## The contract

Every pm and qa skill opens by naming itself:

    Using raftkit-pm:brainstorm to turn this idea into a spec doc.

`raftkit-core/cowork-telemetry` owns the shape, the disclosure, and the boundaries. Each skill carries a one-line bullet pointing at it, the same pattern the plain-language contract already uses.

The line earns its place regardless of measurement. Someone who asked a question and got a differently-shaped answer deserves to know which skill picked it up, and raftkit skills change the shape of a reply a lot. That is also why it is plain text rather than a hidden marker: a tool that measures people should not measure them invisibly.

Walkthrough

The PR adds the Cowork telemetry contract, documents its runtime and opt-out behavior, requires PM and QA skills to announce themselves, updates plugin versions and listings, and adds contract tests.

Changes

Cowork telemetry

Layer / File(s) Summary
Define Cowork telemetry contract
.claude-plugin/marketplace.json, CLAUDE.md, README.md, plugins/raftkit-core/...
The core plugin documents Cowork telemetry, runtime differences, data handling, opt-out behavior, and the cowork-telemetry skill.
Add PM and QA skill announcements
plugins/raftkit-pm/..., plugins/raftkit-qa/...
PM and QA manifests receive version updates. Each listed skill must begin with its Using <plugin>:<skill> identification line.
Validate the telemetry contract
tests/cowork-telemetry.test.sh
The test suite checks registration, announcement format and frequency, skill naming, reporting restrictions, opt-out wording, response handling, and failure reporting.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to f1002

The PR adds mandatory skill announcements, but several existing skills require a different first line or exact standalone output, so those paths cannot satisfy both rules; user responses may be malformed or violate existing contracts until the output rules and assertions are reconciled.

Resolve the announcement and first-output contracts before merge.

The new rule requires Using ... as the first line. Existing rules require a different first line or an exact standalone response. A run cannot satisfy both contracts.

  • plugins/raftkit-pm/skills/estimation/SKILL.md#L142-L142: reconcile the announcement with the mandatory first-line founder-review watermark.
  • plugins/raftkit-pm/skills/user-story/SKILL.md#L152-L152: reconcile the announcement with the first-line watermark for sizing output.

Assert the exact open with instruction for every skill.

CW4 and CW5 only search for the contract name and the skill name anywhere in each file. A skill can pass while its open with \Using ...`` instruction is absent. Then Cowork usage is not recorded.

Check the exact instruction for each derived plugin and skill name.

…data

CI rejected `user-story`'s frontmatter: `amend mode: a diff-first additive edit` puts a bare `": "` inside an unquoted YAML scalar, which ends the scalar early and fails the parse. The skill then loads with empty metadata — no name, no description — so it never triggers at all.

Pre-existing, from b1d4816 (#56). It stayed hidden because a local CLI parses it and the pinned CI one does not, so nothing failed until a PR happened to run validate against a stricter parser.

Fixed with an em dash, and CW11 now scans every skill's frontmatter for the same shape so the next one fails at the test rather than silently shipping a skill that cannot fire. Verified as a real gate: adding a colon to another skill's description fails it by filename.

Only user-story carried it — the scan found one hazard repo-wide.
…ract

Review caught a real conflict. Several skills already own what their first output is: `estimation` opens with the founder-review watermark, and `project-onboarding` and `story-skill-generator` answer an empty state with a message to be reproduced word for word. "Your first line names the skill" contradicted all of them, and a reader resolving that contradiction the other way would drop the announcement and lose the only record the skill ran.

The announcement now has to appear in the first reply, not win a fight over position:

- A required opening line stays the opening line; the announcement follows it.
- "This exact message" constrains the message, not the whole reply — so the announcement may sit either side of it and is never edited into it.
- A hard stop still announces. A skill that refuses is a skill that ran, and an unattributable refusal is the most useful row the dashboard can be missing.

The admin-side matcher already scans the whole response rather than the first line, so nothing changes there.

CW2b pins all four clauses; CW2 follows the reworded contract; CW9 now also requires refusals to be named alongside the read-and-drop promise.
